SuprocessSet::DoWorkWithTimeout()

This patch adds a new method to the SubprocessSet class
to allow it to wait for completed processes with a timeout.
When that happens, this returns the newly-defined ExitTimeout
value.

This will be used by future patches to be able to update the
status periodically even when no edge has completed yet.

Note on lines changes on lines 298 and 345 of subprocess-posix.cc:
The return IsInterrupted() is replaced by return ExitSuccess
because that function would always return false in these cases.

Ninja

Ninja is a small build system with a focus on speed. https://ninja-build.org/

See the manual or doc/manual.asciidoc included in the distribution for background and more details.

Binaries for Linux, Mac and Windows are available on GitHub. Run ./ninja -h for Ninja help.

Installation is not necessary because the only required file is the resulting ninja binary. However, to enable features like Bash completion and Emacs and Vim editing modes, some files in misc/ must be copied to appropriate locations.

If you're interested in making changes to Ninja, read CONTRIBUTING.md first.

Building Ninja itself

You can either build Ninja via the custom generator script written in Python or via CMake. For more details see the wiki.

Python

./configure.py --bootstrap

This will generate the ninja binary and a build.ninja file you can now use to build Ninja with itself.

CMake

cmake -Bbuild-cmake
cmake --build build-cmake

The ninja binary will now be inside the build-cmake directory (you can choose any other name you like).

To run the unit tests:

./build-cmake/ninja_test
